Audio Mixdown Cubase 12 pro. Export range is empty it isn't

Ive been using cubase for over 10 years. with the latest upgrade I keep getting the error “export range is empty”
it isn’t I have clearly defined my left and right locators. the area is a faded blue.
Is this a bug or is there a new process in CB 12?

Hi,

Could you attach a screenshot, please?
